A grey-haired Albert Einstein, portrayed by Fischer Rago, asked students visiting from other classrooms what year they were in. It is 1955 his time, and he is very old and sick.

He told of how he grew up and was educated, but more important were his scientific discoveries. He said he was the first scientist to use the formula E=MC2, and is remembered for his contributions to development of the atomic bomb.

“I’m very sick,” he said. “Nurse, can you bring me a pen and paper?”

Einstein also shared that his son, Hans, is very bright and following in his footsteps.

She explained how she came to marry her husband, and followed him to war. Battles in 1777 and 1778 were hot and Hays brought her pitcher to get water for the soldiers, who were collapsing from the heat.

“Soldiers were yelling, Molly! Molly, pitcher!” she said. “And that became my nickname.”

Hays said her husband collapsed on the battlefield and she took his place at the cannon, which is why George Washington gave her the honor of being a non-commissioned officer.

“I think it was amazing I was given the honor of sergeant,” Hays said.

Grand Duchess Anastasia Nikolaevna Romanov also made an appearance, portrayed by Sophia Puliafico. Anastasia told of her childhood, how she had a tendency to play pranks and was gifted. Her parents did not lavish much on the children, as she slept on a hard cot without a pillow and took cold baths.

She told of the war between Russia and Germany when she was a teenager, and the unforseen tragedy that would befall her family.

“After I turned 17, shortly after midnight, my family was awakened and told to hide in the cellar,” she said.

A Bolshevik firing squad entered and told them the Imperial family was to be executed.

Milton Hershey, portrayed by Jake Johnson, told of his many attempts at making a successful candy company, and offered a Hershey’s Kiss to those who listened intently.

Leonardo DaVinci (Annie Hagen), while painting the Mona Lisa, told of his artistic achievements, but also of how he grew bored of painting and drafted the first flying machine.

“I didn’t get to do all of the things I wanted to do,” he said. “As a well-spent day brings happy sleep, so life well used brings happy death.”

Tony Hawk (Henry Cheng) talked about his early rise to fame with skateboarding, the fallout of the popularity of the sport, and its rising surge. He spoke of the trick he landed — a 300 degree in-air turn — that inspired many to go pro.
